lie it known that I. Isnin JACQUES, a subject ofi the King ot Great Britain, residing at Granby, Province of Quebec, Canada, have invented certain new and useful lmproveinents in Adjustable Dustproof and .lt-ustpro'oit Axles; and I do hereby decla-re that the following is a full, clear, and enact description of the. intention, such as will enable othcrsskilled vin the art to Iwhich it appertains Vto make and use ,the saine.

The present invention pertains to .a novel front axle tor an automobile., designed par#- tic'ularly in .connection with vthe Steering apparatus.

The primary objectoiA the invention is to provide a device of this character wherein the bearing surfaces may be constantly lubri-y cated to prevent rusting and at the same time covered to prevent the entrance ofwater and dirt. In the accomplishment ot this object, one of the fingers of the yoke has a cavity in which is received one of the ends of the spindle bolt. The remaining ond ot the bolt rests on the remaining tinger of the yoke and is formed with a conical cavity. A nut having a conical tip is threaded through the adjacent finger so that the tip fits into the conica-l cavity. Thus, both ends of the spindle bolt are covered by the lingers. A lubricant duct is 'formed lon gitudinally through the bolt, extending to the ends thereof so that it may deliver' to. the bearing surfaces. Lubricant is forcedlnto l the `duct through an oiler carried by the spindle bolt. For the purpose of lockingall the parts together, a pin Vis passed through the spindle bolt and nute having a head at one end and a lock nut at the other.

Another object ot the invention is to provide a bearing between the ends or the spindle bolt and the yoke ngers which maybe adjusted at will and locked inpositi'on to prevent the parts from becoming loose and to compensate tor wear at the bearings. rlhis 'tunction is accomplished by adjustment of the lock nut above referred to.

'I he invention is fully disclosed in the o1` lowing description and in the accompanying drawings in which: Y

Figure 2 is a vertical section thereof;

Figure 3 is a detail section; and,

The Ispindle bol 7 has its upper end'rrclceived in the recess 5 and its lower end rest ing upon the lower linger 4. The wheel spindle 8 is Yintegral with the bolt and eX- tends therefrom at an angle of 90..

A conical recess 9 is cut upwardly from the lower end of the spindle and is normally in alinement with the threaded aperture 6. A nut 10 having a blank conical end 10"is threaded through the aperture G so that this end substantially illsV the conical recess 9. The lower end oi' the bolt is thus fixed to the yoke, while thev upper end is held in the recess 5.

` An oil duct 11 is formed longitudinally through the bolt 7. Through this duct is passed a pin 11, the latter also passing through the nut 10. The threadedend ot the pin, disposed exteriorly of the vnut 10, carries a lock nut 12 and a lock washer 12 interposed between the nuts 10 and 12. A communicating Iduct 13 entends from the duct 11 axially along the spindle 8 and has a short branch l5 leading to the surface of the spindle.. Access to the passage 11v is obtained by means ol an oiler 16 supported at the Lipper end of the spindle bolt 7.

In the use of the device, oil is forced into lthe main duct 11. and communicating branches through the oiler 16.

fFrom the duct 11 the lubricant enters the cavity 5 to lubricate the upper end ofthe spindle bolt and also enters between t-he conical surfaces of the recess 9 and nut end 10 to lubricate the parts in this region. These bearings, being completely covered by the fingers 3 and Zl, render the device dustproof land waterproof,` and also keep the moving parts constantly lubricated. Obvi- @fnds @farisei easiest all Aupper- Yil) ously, the lubricant Will also flow throuvh oi the spindle bolt 7. In this inannei, the. bearing surfaces at the ends of the spindle boltare constantly `maintained in dustprooi and waterproof condition.

lVhile a specilic embodiment of the invention has been. illustrated and described, it is to be understood that various alterations in the details or construction may be made Without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully describedv the 'invention, whatI claini as new vand desire to protect by Letters Patent is l. A dust and rustproof'axle comprising a yoke `having-a pair of fingers extending therefrom, one of said lingers having a cavity lformed in its inner surface, theremaining linger havingV a threaded aperture, a spindle having oneend received in Said cavity and its remaining end resting on the apertured linger, said remaining end havinO' `a conical cavity, a nut threaded through saidapertnre and having a conical end received in'said conicalcavity, said bolt having a lubricant duct formed longitudinally therethrough and a pin loosely fitted in said duct andmsecnred to said nut and the opposite linger.v

' 2. A dust and rnstproo axle comprising a yoke having an upper and a lower linger, said upper finger having a cavity cut therein, a spindle bolt having one end received in said cavity and the remaining end resting on the lon-er'liiiger, said lower linger having'l a threaded aperture, the lower end of the bolt having -aiconical recess, a nut threaded' through said aperture and having' a conical end'A received in saidfconical recess, said bolt having a lubricant duct formed longitudinally therethrough, and a pin loosely litted in said duct and secured to said nut and the opposite finger.` Y

In Wit-ness whereof I have hereunto set my hand.
